To al'whom 'it mayV concern Be itk'n'own that I, lIsmo'u Krrsnn, a citizen of the United States, resi ing at Philadelphia, in the county of Philadelphia and lState of Pennsylvania, have invented certain new and useful Improvements in ElectricTransmission'of Intelligence, of which the following isa specifica `on.

My invention relates totian improvement inelectric transmission of lintelligenc'e. Its .object is, .to provide means 'so .as to-reduce, orto eliminate entirelyv the inductive eifect fof wires carrying aV current for light orl ower on lmes of transmission, and this, my mvention, has more Vspecilal reference to such 1, `1, 1, are the lines of dtransmissiolrfconnected together electrically ment," the line is-eas far as the eil'ect of the but notconductively through the condensers 3, 3, 3, and connected also with the interposition of such condensers 3, 3, 3, to the line 2, which I 'call the, idle line vor return.

In the drawing, 5 designates the power or inducing line. When the lines of transmission are not connected with each other and witna conductor not in the region of inducing influence, the elect of the inducing current'is augme ted in nearly equal propor- -tion'ito the le gth of the line, that is, the longerthe line, vthe greater the ellect at the 4teminals,oisaid line. With my arrangeinducing cupi/'ents are concerned-divided into aseries/of sections,l eachsection only comprising a small length of the line.

In the idrawing, Iv have illustrated only' one section of a line and this section is subdivided ihto live. sub-sections; thesection is, as stated above, only a small part of the line and does not need to be shorter than about olie thousand feet; each sub-section, therefort, would comprise a length of wire of about two hundred 'feet Certainly, these iigure's are only given as a guide and may be altered to suit requirements. It 1s now sup posed that the inducing current has induced `in the line, that is, in each or' the sections, an

impulse flowing in the direction. of the unfeathered arrow. The impulses induced in one of these sections will not `flow through the whole length of the line, but they will flow-in the circuit composed of the line .sections. Instead, therefore, to have a comparatively long line with augmented induced impulses, we have a series'of comparatively short lines in which the induced impulses have a complete circuit of their 0WD.' should be removed from the zone of inductive influence and it is best, if this line is buried under ground, to insulate the same, as it was found that purely ground connections do not serve the purpose as well. If required, a choking coil may be inserted in the line between the ,different sections and.

I have designated such coil by the numcral 4.-.

It has to be stated, that the line 2,'

Having now described my. invention, what I claim as new and desire tev secure by Let-- ters Patent is:

l. Means to nullii'y the inducing effect of i a power Wire on lines of transmission, said means comprising condensers connecting the lines of transmission to each other, impedance for each of said linesI of transmission and a metallic return connecting electrically all the lines of transmission, said return line removed from the zones of the first named lines.

2. A series of telegraphic lines electrically but not conductively connected with each other at di il'erent points, in combination with a metallic line removed from the zones of fthe first lines and connected electrically to all of the first lines. In testimony whereof I allix I'ny signature 1n presence of two Witnesses.
